Unlike California’s majestic rivers and massive dams and
conveyance systems, groundwater is out of sight and underground,
though no less plentiful. The state’s enormous cache of
underground water is a great natural resource and has contributed
to the state becoming the nation’s top agricultural producer and
leader in high-tech industries.
Groundwater is also increasingly relied upon by growing cities
and thirsty farms, and it plays an important role in the future
sustainability of California’s overall water supply. In an
average year, roughly 40 percent of California’s water supply
comes from groundwater.
A new era of groundwater management began in 2014 with the
Sustainable Groundwater Management Act, which requires local
and regional agencies to develop and implement sustainable
groundwater management plans with the state as the backstop.
A northern Fresno County groundwater agency is ramping up
efforts to help landowners register their wells by hosting the
first in a string of workshops on Aug. 27. Dates for future
workshops are still in flux. Owners of water wells in the
greater Kerman, Biola, Easton, Fresno and Clovis areas are
invited to the workshop, from 3-6 p.m. at the Kerman Community
Center, 15101 W Kearney Blvd. The North Kings Groundwater
Sustainability Agency board of directors issued a
mandatory well registration policy in April. All well owners
must register by Nov. 30, 2025 to avoid a $100 penalty per
well.
… The Tehama County Groundwater Commission and the Tehama
County Flood Control and Water Conservation District Board of
Directors, serving as the region’s Groundwater Sustainability
Agency (GSA), continues to work on the county’s state-required
Groundwater Sustainability Plan (GSP). … Since the start of
the GSP process, the county’s GSA has been plagued with issues
associated with the plan, its development and implications. The
2023 Tehama County Grand Jury in its findings determined the
fee assessment of .29 cents an acre placed on well owners in
the county was faulty in the areas of inequitable fees,
inadequate communication, accountability and other
issues.
Landowners who rely on domestic wells for drinking water may be
able to seek help from the Mid-Kings River Groundwater
Sustainability Agency if the tap runs dry. In an Aug. 12 board
meeting, the GSA unanimously approved a $2 million program to
help owners repair wells damaged by excessive groundwater
pumping and keep water flowing to residents. … In April
2024 the state Water Resources Control Board put the region on
probation for lacking an adequate groundwater plan. A month
later, Mid-Kings imploded after the Kings County Water District
bailed and the county was left to pick up the pieces.
Without a water tax, the Paso Robles Area Groundwater Authority
is on the hunt for funding to support its operating costs for
the rest of the year. The agency’s Board of Directors was
forced to abandon water use fees during a meeting on Aug. 1
after a majority of property owners objected to them. Now, the
agency is almost $300,000 short of funds needed to cover the
rest of the year’s operating costs, such as paying consultants
and preparing the state-mandated annual report. … During
a meeting on Monday, the board voted unanimously to direct
staff to send a request to the four participating groundwater
sustainability agencies to bridge the funding gap.
… Decades of unreliable surface water left San Joaquin Valley
farmers no choice but to pump groundwater — with severe
consequences. Sinking land, cracked infrastructure and reduced
capacity to the California Aqueduct that delivers water to
millions in Southern California. The good news: Subsidence can
be slowed — and potentially reversed. Since 2023, Westlands’
farmers recharged over 470,000 acre-feet of groundwater,
restoring water levels by 200 feet in some areas. Injection
wells have lifted land by half a foot. In one important
location, subsidence stopped completely. –Written by Allison Febbo, general manager of the
Westlands Water District.
Years of collapsing areas of land in the San Joaquin Valley —
caused primarily by the over-pumping of groundwater for farming
— has taken a toll on California’s largest water delivery
system that relies on stable land to work well. A state report
released this year determined its 2023 annual water delivery
capability had fallen 3% compared to original-design
deliveries. If no action is taken, it could fall up to 87% by
2043. If that happens, 21 million Californians would feel the
impacts, according to the California Department of Water
Resources (DWR).
An Arizona judge has ruled a coalition of farms and
municipalities can’t jump into a lawsuit the state has brought
against Saudi Arabian-backed farming company Fondomonte.
Arizona Attorney General Kris Mayes is suing Fondomonte in
Maricopa County Superior Court on claims its groundwater
pumping is a “public nuisance.” … In his ruling, Judge
John Blanchard acknowledged this is seen as a “test case” for
enforcing groundwater regulation, but said “generalized
concern” about potential future lawsuits isn’t a good enough
reason to let the other groups intervene.
A California court just confirmed that groundwater rights pass
with the land in foreclosure, settling a major question for
commercial mortgage professionals statewide. … The
dispute began in 2017, when 4-S Ranch Partners, LLC secured a
$33 million loan from Sandton Credit Solutions. … However, by
2019, 4-S Ranch had defaulted on the loan. … Sandton
sought a court declaration that all rights to the groundwater
passed with the land at foreclosure. 4-S Ranch continued to
argue that the groundwater was personal property and should not
have transferred with the land. The trial court ruled in
Sandton’s favor. … On August 8, 2025, the Fifth District
Court of Appeal affirmed the trial court’s decision.
Sinking ground in California’s Central Valley is causing
property values to sink, according to a new study by UC
Riverside. ”When we see droughts, we see larger
subsidence, we see more extraction of groundwater, we see
larger subsidence, and that’s a sign for many other problems,
like water availability, job availability and so on,” said
Mehdi Nemati, author and UC Riverside Enviro Economics and
Policy assistant professor. … To determine how this
sinking is impacting home values, researchers used
satellite-based radar data to measure ground-level changes. …
They estimated that losses totaled $1.87 billion across the
region from 2015 to 2021.
The state Water Resources Control Board reversed course on a
proposed fee change for groundwater extraction in the San
Joaquin Valley after receiving a volley of negative letters,
saying changes are “premature.” The update came during an
online Water Rights Fees meeting July 31. Fees target pumpers
in overdrafted subbasins placed on probation by the Water Board
for lacking adequate groundwater plans. State fees … are
intended to repay the state an estimated $5.5 million a year
that it says it costs to oversee six groundwater basins in the
San Joaquin Valley where plans have been deemed
inadequate. Water Board staff had suggested creating a
graduated fee structure based on farm size, giving small
growers a break at $5-per-acre-foot pumped and charging large
growers $40 per acre foot pumped.
… [Sen. Adam] Schiff was here this week to host the
Tahoe Summit, an annual event where lawmakers and community
leaders gather at a lakefront venue to champion environmental
protections, bipartisan collaboration and federal investment in
Lake Tahoe. This year, calls to protect Lake Tahoe come as the
Trump administration cuts funding for climate change research
and reduces staffing at public land management agencies.
… Schiff, who sits on the Senate’s agriculture
committee, told SFGATE on Tuesday aboard the John LeConte that
he is “deeply concerned” about cuts to the Forest
Service. … [H]e told SFGATE he wants to carry on [former
Sen. Dianne] Feinstein’s legacy and continue to advocate for
Lake Tahoe.
Assembly Bill 1413 seeks to quietly rewrite California’s water
laws, raising alarm among local water agencies, business
groups, lawmakers and many advocates of California’s
agriculture industry. The Indian Wells Valley Water District in
eastern Kern County has serious concerns about the proposal’s
threats to groundwater rights, due process, transparency and
scientific accountability. The bill would limit judicial
oversight and fundamentally alter the role of groundwater
sustainability plans in California, potentially treating them
as a legally binding determination of water rights. The Indian
Wells water district is undergoing an adjudication process to
protect property rights, and officials like me worry that AB
1413 would prohibit courts from reviewing the science behind
these plans, as well as potential errors. –Written by David Saint-Amand, board president of the
Indian Wells Valley Water District.
As California’s farmers adjust to restrictions on groundwater
pumping under the Sustainable Groundwater Management Act
(SGMA), tools to foster adaptation can be a big help.
Groundwater markets are one promising tool, but how can
groundwater sustainability agencies (GSAs) design groundwater
markets to protect those who might be affected by trading?
… The flexible, decentralized nature of markets makes
them powerful, but they can be unpredictable. Groundwater
markets need clear rules that support SGMA, prevent
overpumping, and reduce local economic impacts. Good market
design requires careful thought, planning, and communication
with farmers and the broader community.
… According to a study released last week in the
peer-reviewed academic journal Science Advances, fresh water
has been declining at an alarming rate since researchers began
observing global groundwater in 2002, creating areas of
“mega-drying” that cover much of the Northern Hemisphere.
… The United States, which sources half of its
drinking water from groundwater, has no unifying water
management plan, instead relying on a piecemeal local network
of regulations. California passed the Sustainable
Groundwater Management Act, which aims to regulate
water withdrawals and prevent aquifer exhaustion, in 2014, but
the state isn’t expected to reach sustainable water use
patterns until the early 2040s.
… I understand and support the intent behind SGMA; conserving
groundwater is essential to the long-term survival of
agriculture in this state. But the reality is stark: as SGMA is
implemented, vast swaths of productive farmland—nearly a
million acres statewide—are being fallowed, with no clear
economic alternative for the land or the people who rely on it.
… AB 1156 would allow landowners to lease fallowed land
for clean energy development through updated solar use
easements. It provides a stable, dependable source of income to
support families, workers, and communities—while still honoring
the land. –Written by Cameron Moors, manager of Renton and Terry
Farms LLC and co-founder and business development officer of
SunHarvest Partners.
The Paso Robles Area Groundwater Authority was forced to
abandon water use fees during a tense meeting Friday after a
majority of property owners overwhelmingly objected to them.
This means that people pumping from the basin still won’t have
to pay for their water use. … As of Friday, 689 of the 1,283
impacted parcels submitted protests for the fees — the majority
vote needed to stop the Board of Directors from voting on the
rates. … Because the basin is considered “critically
overdrafted” by the California Department of Water Resources,
the Paso Robles Area Groundwater Authority is required to bring
the basin into balance by 2040. The fees were designed to
fund state-mandated tasks like monitoring wells and writing
annual reports, along with new programs designed to support
farmers, dry well owners and balance the basin.
A western Fresno County groundwater agency hopes to increase
pumping fees by about 212%, from $8 per acre foot to $25 per
acre foot, in a bid to avoid state intervention. The Pleasant
Valley Groundwater Sustainability Agency (GSA) board agreed at
its July 29 meeting to put the proposed fee hike to a vote of
its growers through a Proposition 218 election, which is
required before increasing land assessment or pumping
fees. A hearing is scheduled for Oct. 28 where growers can
protest the proposed increase. If the pumping fee hike
succeeds, the Pleasant Valley Water District, which also acts
as the GSA, would reduce existing land assessment fees from $6
per acre to $3.25 per acre. The money from the pumping fee is
needed, according to GSA board members, to pay for a revised
groundwater plan. The Department of Water Resources deemed
the region’s existing plan inadequate in
February.
… Cadiz recently alleged that its efforts to access and pump
out groundwater are not subject to review by California’s State
Lands Commission. But in June, incoming Senate President
Monique Limón and Assemblymember Isaac Bryan, both of whom
chair the California Legislature’s committees on natural
resources, quashed that evasion. … The lawmakers
highlighted the strict and detailed scrutiny facing the company
under state law. … Gov. Newsom championed that law. This
week is the sixth anniversary of SB 307, which he signed on
July 31, 2019. In his signing statement, the Governor stated
the fact that “water has flowed underneath the Mojave for
thousands of years,” feeding a “fragile ecosystem.”
A Bay Area representative and other federal lawmakers mounted a
push on Tuesday for action on groundwater
rise, which they warned will worsen flooding across
the United States in the decades to come, with the potential to
damage critical infrastructure, harm freshwater supplies and
spread toxic chemicals into communities. … U.S. Reps.
Kevin Mullin, D-San Mateo, and Andrew Garbarino, R-N.Y.,
introduced legislation in June that would set aside $5 million
over the next year for the United States Geological Survey to
study and map groundwater rise nationally through 2100. …
They held a press conference on Tuesday in South San Francisco
in San Mateo County — considered the most at-risk county to sea
level rise in California — to push for
Congress to advance the legislation, which they dubbed the
Groundwater Rise and Infrastructure Preparedness Act of 2025.
The continents are rapidly drying out and the earth’s vast
freshwater resources are under threat, according to a recently
released study based on more than 20 years of NASA satellite
data. … The study, published in the journal Science
Advances, examined changes to Earth’s total supply of fresh
water and found that nearly 6 billion people live in the 101
countries facing a net decline in water supply, posing a
“critical, emerging threat to humanity.” According to the
study, the uninhibited pumping of groundwater by farmers,
cities and corporations around the world now accounts for 68%
of the total loss of fresh water at the latitudes where most
people live.
Fresno County’s west rural communities of Cantua Creek, El
Povernir, and Five Points are at the epicenter of California’s
clean energy transition and the world’s largest solar project.
The California Energy Commission (CEC) last month approved the
Darden Clean Energy Project (DCEP). … Environmental
justice groups had raised concerns whether the transition from
agriculture to energy production would be
equitable for the communities’ residents. Environmental
advocates said the residents in the communities neighboring the
project already face challenges such as undrinkable and
unaffordable water, extreme heat, and historical
disinvestment. … The solar power plant will be built on 9,500
acres of land in unincorporated western Fresno County that is
no longer able to support agricultural production. The land was
owned by the Westlands Water District.
Pacific Gas & Electric Co. submitted a request to federal
regulators Friday to tear down an aging hydroelectric project
in Mendocino and Lake counties, a $530 million
demolition that would include removal of two dams on the
Eel River. The Potter Valley Project, according to PG&E, is
no longer financially fit for power generation. However, the
project’s greatest asset has become the water it provides, and
the beneficiaries of that water, which include cities and towns
in Sonoma and Marin counties as well as the region’s celebrated
grape-growing industry, have been on edge about losing
supplies. … Under PG&E’s proposal, a new agency run
by local communities would take over some of the existing
project facilities and continue water shipments. The agency,
though, wouldn’t be able to ship as much water and would likely
charge more for it.
Newly released state guidelines on how to get a handle on
subsidence, or land sinking, were received with mixed reactions
after they were released by the Department of Water Resources
on Thursday. The guidelines provide some basic, but pointed,
advice on how San Joaquin Valley groundwater managers can best
stop, slow or even reverse subsidence, which a 2014 report
shows had cost billions of dollars up to that time in history.
Managers should put more water, lots more, into withered
aquifers to bring land elevations back up, according to the new
guidelines. … One groundwater agency or water district can’t
fix the problem without help from surrounding districts, the
new guidelines state.
For almost a century, parts of California have been gradually
sinking, impacting critical infrastructure and the communities
who rely on it. Recognizing this challenge, the Department of
Water Resources has released a draft Best Management Practices
document for public comment that will help local water
agencies address this growing concern and support groundwater
reliant communities. … Once finalized following public
review, the document will serve as a guide for groundwater
managers on the basics of subsidence, how to best manage it,
and available technical assistance. This document does not
replace any existing, local, state, or federal regulations, but
serves as a resource that local agencies can add to their water
management toolkit.
Property owners who pump water for their farms or businesses
from the Paso Robles Area Groundwater Basin may soon need to
pay for their groundwater. Right now, they have the opportunity
to protest those fees. Residential well owners, however,
won’t be charged those fees directly — which means they can’t
protest them either, according to Ryan Aston, a consultant who
developed the proposed rates. … The agency will hold a
public hearing to consider the rates on Aug. 1. If a majority
of recipients submit a written protest, the agency can’t
implement the rates. Otherwise, the board can vote to enact the
fees.
… Much of Marin County’s spiderweb of coastal and bayside
transit options is at risk of inundation from rising sea levels
in the coming decades, according to a recent study identifying
the climate vulnerabilities of its built infrastructure. The
county, surrounded by water on three sides, is already plagued
by flooding during high tides several times a year. Now it has
a greater understanding of its future sea level rise risk due
to the effects of human-caused climate change, thanks to the
study unveiled last week by the Transportation Authority of
Marin, or TAM, in collaboration with environmental consulting
firm Arup. Researchers identified 19 areas along the Marin
County shoreline that are prone to flooding, sea level rise and
groundwater rise, noting that “tipping points”
at which flooding becomes permanent are just decades out in
some locations.
Farmers in the Eastern Tule Groundwater Sustainability Agency
(GSA) can see a light at the end of the tunnel as county
administrators begin to execute a rescue plan to help them
comply with the state’s groundwater law. Assembly Bill
568 made it through the state Senate Natural Resources and
Water Committee July 16. If approved by Gov. Gavin Newsom, the
legislation will create the new Tule East GSA, a joint powers
authority between Tulare County, Hope and Ducor Water
Districts. … The new entity will encompass about half
the acreage of Eastern Tule, almost all groundwater-dependent
lands that were left behind when irrigation districts abandoned
the GSA in the wake of the state Water Resources Control
Board’s decision to place the Tule subbasin on probation in
September.
Lawmakers are poised to give California’s water districts legal
cover from lawsuits as they work to meet strict new state
standards for a cancer-causing toxic chemical. It’s
called hexavalent chromium, more commonly known as
“chromium-6.” Drinking water with trace amounts of the chemical
over long periods has been linked to cancer. Last year,
state water regulators approved a nation-leading drinking water
standard for the chemical, which is found naturally in some
California groundwater. In other areas, chromium-6 leached into
the water from industrial sites. The regulations are
intended to protect more than 5 million Californians from the
toxin, including in the Central Valley, Inland Empire and along
the coast. Water districts say they plan to comply, but they
complain the new rules are going to cost tens of millions of
dollars, will jack up their customers’ water bills and could
take years to complete.
While some groundwater managers in the beleaguered Tulare Lake
subbasin look for ways to come together on pumping limits in
order to comply with state mandates, the giant J.G. Boswell
Farming Company has remained silent and intractable. The
company, which controls the El Rico Groundwater Sustainability
Agency (GSA), still plans to allow so much groundwater pumping
within its boundaries that it could sink the old Tulare Lake
bed – including the small town of Corcoran – by another
10 feet. That’s only a foot less than it planned back in 2021
when the subbasin, which covers most of Kings County, submitted
its first management plan required under the Sustainable
Groundwater Management Act (SGMA).
Buckeye and Queen Creek can now access groundwater from a
farming area in western Phoenix. The move comes after officials
from the Department of Water Resources approved the first-ever
legal transfer of water from rural Arizona to cities. The
agreement will allow the communities of Buckeye and Queen Creek
to withdraw up to 5,926 acre-feet per year and 5,000 acre-feet
per year, respectively from the Harquahala basin. Still, the
question remains as to whether this is a permanent
solution. Sarah Porter is the director of the Kyl Center
for Water Policy at Arizona State University. She says this
inter-basin transfer isn’t a total answer to ensuring that
Arizona has enough water to continue to grow.
The Imperial Irrigation District has taken a stance on where
solar energy projects should go. The board passed a resolution
saying too much farmland in the Imperial Valley is being
replaced with solar panels. Most of the power from these
projects goes to big cities like San Diego, not the local
community. IID officials say they support solar development,
but not at the expense of agriculture. “One in every six jobs
in the Imperial Valley is directly related to agriculture, so
solar is great, as long as it’s not on ag land,” said Robert
Schettler with IID. The district also says farmland plays a
role in helping the Salton Sea. “When growers
grow, whatever the size of their farmland is, one third of the
water that goes onto the field drains off and goes to the
Salton Sea, so if you take ag out of production you’re not only
affecting the local economy, you’re affecting the Salton Sea,”
said Schettler. … IID is encouraging future solar
projects to be built on desert or unused land instead.
Sonoma County’s groundwater is quietly
vanishing beneath our feet, and the numbers are alarming. In
parts of Sonoma Valley, deep aquifers have plummeted nearly 100
feet in the last decade, according to recent reports from the
Sonoma Valley Groundwater Sustainability Agency (GSA). With
some wells dropping as much as eight feet per year, residents
and businesses alike have good reason to be worried. …
Drilling a new well can cost $50,000 or more, a financial blow
that smaller family-run vineyards find especially daunting.
Sonoma Valley has responded by expanding a recycled water
pipeline on the east side, delivering treated wastewater for
irrigation and reducing pressure on depleted aquifers.
… The county is experimenting with Aquifer Storage
and Recovery (ASR), injecting excess treated Russian River
water underground during rainy months, banking it for future
dry spells.
California farmers, agricultural commissioners and lawmakers
have in recent months sounded an alarm about a troubling
symptom of the state’s struggling farm economy.
“Everywhere you turn there’s an abandoned vineyard,” said Randy
Baranek, project manager for the Stanislaus County-based
agricultural service provider Fowler Brothers. He estimated
there are twice as many untended grapevines in the Central
Valley this year than he has ever seen. … The phenomenon has
led to widespread concern that pests harbored in abandoned
orchards and vineyards could impact adjacent
farms. … Farmers cautioned that the situation could
get worse before it improves. While almond prices have improved
this year, the winegrape market has not. Meanwhile, limits
on groundwater pumping under California’s Sustainable
Groundwater Management Act have led some growers in parts of
the San Joaquin Valley to begin abandoning orchards.
El Verano and eastern Sonoma Valley face worsening groundwater
shortages, leading officials to designate those regions as
Groundwater Sustainability Priority Areas requiring stronger
conservation efforts. The Sonoma Valley Groundwater
Sustainability Agency made the announcement in June following
years of observing the continously declining water levels in
the Valley’s deep aquifers, some of which have dropped by
nearly 100 feet over the last decade. In the most severely
impacted zones, groundwater levels are falling by as much as 8
feet per year, officials say. … The primary cause of the
crisis is over-pumping of deep aquifers — those more than 200
feet below ground — which recharge significantly slower than
shallow aquifers.
The Imperial Irrigation District, which provides water to
farmers in the southeastern corner of California, drew a
figurative line in the sand earlier this month, calling for a
halt to the conversion of agricultural fields into solar panel
farms. … The state Department of Conservation says that
agricultural lands declined by more than 1.6 million acres
between 1984 and 2018, averaging 47,000 acres a year. The most
productive land experienced the largest
decline. … As farmers, particularly the larger
corporate growers, take land out of production, many believe
that their economic salvation lies in solar panel arrays that
generate the emission-free electricity that the state wants, as
it phases out power fueled by hydrocarbons. However, that
doesn’t sit well with farmers who want to continue production,
as the Imperial Irrigation District’s call for a solar
moratorium implies. –Written by CalMatters columnist Dan Walters.
Unsustainable groundwater overpumping in
California has triggered the need to transition hundreds of
thousands of acres of irrigated agricultural land into less
water-intensive activities to make water use
sustainable. … After years of work done by our
community of practice and scientists, we just published a much
needed and comprehensive framework for best practices in
cropland repurposing that can benefit everyone involved. This
community of practice includes community leaders, farmer and
farmworker advocates, scientists, and practitioners across
California’s agricultural regions. … In addition to our
recent Roadmap for a Just Land Transition, our team of 54
coauthors (with the help of many collaborators and participants
in public events) published a paper introducing a framework for
best practices in cropland repurposing in the journal Frontiers
in Water. In the next sections of this blog I will briefly
summarize some of the most important takeaways from this work.
Cities across California and the Southwest are significantly

Seeking to prevent the California State Water Resources Control
Board from stepping in to regulate groundwater in critically
overdrafted subbasins, local agencies are working to correct
deficiencies in their plans to protect groundwater. With
groundwater sustainability agencies formed and groundwater
sustainability plans evaluated, the state water board has moved
to implement the 2014 Sustainable Groundwater Management Act,
or SGMA. … Under probation, groundwater extractors in
the Tulare Lake subbasin face annual fees of $300 per well and
$20 per acre-foot pumped, plus a late reporting fee of 25%.
SGMA also requires well owners to file annual groundwater
extraction reports.
This tour explored the lower Colorado River firsthand where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to some 40 million people in the Southwest across seven states, 30 tribal nations and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

Last week, Assemblywoman Esmeralda Soria introduced AB 2060 to
help divert local floodwater into regional groundwater
basins. AB 2060 seeks to streamline the permitting process
to the California Department of Fish and Wildlife in support of
Flood-MAR activities when a stream or river has reached
flood-monitor or flood stage as determined by the California
Nevada River Forecast Center or the State Water Resources
Control Board (SWRCB). This expedited approval process would be
temporary during storm events with qualifying flows under the
SWRCB permit.
How will selling groundwater help keep more groundwater in the
San Joaquin Valley’s already critically overtapped aquifers?
Water managers in the Kaweah subbasin in northwestern Tulare
County hope to find out by having farmers tinker with a pilot
groundwater market program. Kaweah farmers will be joining
growers from subbasins up and down the San Joaquin Valley
who’ve been looking at how water markets might help them
maintain their businesses by using pumping allotments and
groundwater credits as assets to trade or sell when water is
tight.

The 3ʳᵈ International Conference, Toward Sustainable Groundwater in Agriculture: Linking Science & Policy took place from June 18 – 20. Organized by the Water Education Foundation and the UC Davis Robert M. Hagan Endowed Chair, the conference provided scientists, policymakers, agricultural and environmental interest group representatives, government officials and consultants with the latest scientific, management, legal and policy advances for sustaining our groundwater resources in agricultural regions around the world.
The conference keynote address was provided by Mark Arax, an award-winning journalist and author of books chronicling agriculture and water issues in California’s Central Valley. Arax comes from a family of Central Valley farmers and is praised for writing books that are deeply profound, heartfelt and nuanced including The Dreamt Land, West of the West and The King of California. He did a reading from his latest book The Dreamt Land and commented on the future of groundwater in the Valley during his keynote lunch talk on June 18.

A new but little-known change in
California law designating aquifers as “natural infrastructure”
promises to unleash a flood of public funding for projects that
increase the state’s supply of groundwater.
The change is buried in a sweeping state budget-related law,
enacted in July, that also makes it easier for property owners
and water managers to divert floodwater for storage underground.
A new underground mapping technology
that reveals the best spots for storing surplus water in
California’s Central Valley is providing a big boost to the
state’s most groundwater-dependent communities.
The maps provided by the California Department of Water Resources
for the first time pinpoint paleo valleys and similar prime
underground storage zones traditionally found with some guesswork
by drilling exploratory wells and other more time-consuming
manual methods. The new maps are drawn from data on the
composition of underlying rock and soil gathered by low-flying
helicopters towing giant magnets.
The unique peeks below ground are saving water agencies’
resources and allowing them to accurately devise ways to capture
water from extreme storms and soak or inject the surplus
underground for use during the next drought.
“Understanding where you’re putting and taking water from really
helps, versus trying to make multimillion-dollar decisions based
on a thumb and which way the wind is blowing,” said Aaron Fukuda,
general manager of the Tulare Irrigation District, an early
adopter of the airborne electromagnetic or
AEM technology in California.

It was exactly the sort of deluge
California groundwater agencies have been counting on to
replenish their overworked aquifers.
The start of 2023 brought a parade of torrential Pacific storms
to bone dry California. Snow piled up across the Sierra Nevada at
a near-record pace while runoff from the foothills gushed into
the Central Valley, swelling rivers over their banks and filling
seasonal creeks for the first time in half a decade.
Suddenly, water managers and farmers toiling in one of the
state’s most groundwater-depleted regions had an opportunity to
capture stormwater and bank it underground. Enterprising agencies
diverted water from rushing rivers and creeks into manmade
recharge basins or intentionally flooded orchards and farmland.
Others snagged temporary permits from the state to pull from
streams they ordinarily couldn’t touch.
This special Foundation water tour journeyed along the Eastern Sierra from the Truckee River to Mono Lake, through the Owens Valley and into the Mojave Desert to explore a major source of water for Southern California, this year’s snowpack and challenges for towns, farms and the environment.
This tour explored the Sacramento River and its tributaries through a scenic landscape while learning about the issues associated with a key source for the state’s water supply.
All together, the river and its tributaries supply 35 percent of California’s water and feed into two major projects: the State Water Project and the federal Central Valley Project.

A pilot program in the Salinas Valley run remotely out of Los Angeles is offering a test case for how California could provide clean drinking water for isolated rural communities plagued by contaminated groundwater that lack the financial means or expertise to connect to a larger water system.
Managers of California’s most
overdrawn aquifers were given a monumental task under the state’s
landmark Sustainable Groundwater Management Act: Craft viable,
detailed plans on a 20-year timeline to bring their beleaguered
basins into balance. It was a task that required more than 250
newly formed local groundwater agencies – many of them in the
drought-stressed San Joaquin Valley – to set up shop, gather
data, hear from the public and collaborate with neighbors on
multiple complex plans, often covering just portions of a
groundwater basin.

An online
short course starting Thursday will provide
registrants the opportunity to learn more about how groundwater
is monitored, assessed and sustainably managed.

Martha Guzman recalls those awful
days working on water and other issues as a deputy legislative
secretary for then-Gov. Jerry Brown. California was mired in a
recession and the state’s finances were deep in the red. Parks
were cut, schools were cut, programs were cut to try to balance a
troubled state budget in what she remembers as “that terrible
time.”
She now finds herself in a strikingly different position: As
administrator of the U.S. Environmental Protection Agency’s
Region 9, she has a mandate to address water challenges across
California, Nevada, Arizona and Hawaii and $1 billion to help pay
for it. It is the kind of funding, she said, that is usually
spread out over a decade. Guzman called it the “absolutely
greatest opportunity.”
This tour explored the lower Colorado River firsthand where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.
The 1,450-mile river is a lifeline to some 40 million people in the Southwest across seven states, 30 tribal nations and Mexico. How the Lower Basin states – Arizona, California and Nevada – use and manage this water to meet agricultural, urban, environmental and industrial needs was the focus of this tour.

This tour ventured through California’s Central Valley, known as the nation’s breadbasket thanks to an imported supply of surface water and local groundwater. Covering about 20,000 square miles through the heart of the state, the valley provides 25 percent of the nation’s food, including 40 percent of all fruits, nuts and vegetables consumed throughout the country.

As California’s seasons become
warmer and drier, state officials are pondering whether the water
rights permitting system needs revising to better reflect the
reality of climate change’s effect on the timing and volume of
the state’s water supply.
A report by the State Water Resources Control Board recommends
that new water rights permits be tailored to California’s
increasingly volatile hydrology and be adaptable enough to ensure
water exists to meet an applicant’s demand. And it warns
that the increasingly whiplash nature of California’s changing
climate could require existing rights holders to curtail
diversions more often and in more watersheds — or open
opportunities to grab more water in climate-induced floods.
The San Joaquin Valley has a big
hill to climb in reaching groundwater sustainability. Driven by
the need to keep using water to irrigate the nation’s breadbasket
while complying with California’s Sustainable Groundwater
Management Act, people throughout the valley are looking for
innovative and cost-effective ways to manage and use groundwater
more wisely. Here are three examples.
Groundwater provides about 40
percent of the water in California for urban, rural and
agricultural needs in typical years, and as much as 60 percent in
dry years when surface water supplies are low. But in many areas
of the state, groundwater is being extracted faster than it can
be replenished through natural or artificial means.
Across a sprawling corner of southern Tulare County snug against the Sierra Nevada, a bounty of navel oranges, grapes, pistachios, hay and other crops sprout from the loam and clay of the San Joaquin Valley. Groundwater helps keep these orchards, vineyards and fields vibrant and supports a multibillion-dollar agricultural economy across the valley. But that bounty has come at a price. Overpumping of groundwater has depleted aquifers, dried up household wells and degraded ecosystems.
Since 1997, more than 430 engineers,
farmers, environmentalists, lawyers, and others have graduated
from our William R. Gianelli Water Leaders program. We’ve
developed a new alumni network
webpage to help program participants connect and keep in
touch.

The bill is coming due, literally,
to protect and restore groundwater in California.
Local agencies in the most depleted groundwater basins in
California spent months putting together plans to show how they
will achieve balance in about 20 years.
This event explored the lower Colorado River where virtually every drop of the river is allocated, yet demand is growing from myriad sources — increasing population, declining habitat, drought and climate change.

Innovative efforts to accelerate
restoration of headwater forests and to improve a river for the
benefit of both farmers and fish. Hard-earned lessons for water
agencies from a string of devastating California wildfires.
Efforts to drought-proof a chronically water-short region of
California. And a broad debate surrounding how best to address
persistent challenges facing the Colorado River.
These were among the issues Western Water explored in
2019, and are still worth taking a look at in case you missed
them.
A diverse roster of top
policymakers and water experts are on the
agenda for the Foundation’s 36th annual Water
Summit. The conference, Water Year 2020: A Year
of Reckoning, will feature compelling conversations
reflecting on upcoming regulatory deadlines and efforts to
improve water management and policy in the face of natural
disasters.
Tickets for the Water Summit are sold out, but by joining the waitlist we can

To survive the next drought and meet
the looming demands of the state’s groundwater sustainability
law, California is going to have to put more water back in the
ground. But as other Western states have found, recharging
overpumped aquifers is no easy task.
Successfully recharging aquifers could bring multiple benefits
for farms and wildlife and help restore the vital interconnection
between groundwater and rivers or streams. As local areas around
California draft their groundwater sustainability plans, though,
landowners in the hardest hit regions of the state know they will
have to reduce pumping to address the chronic overdraft in which
millions of acre-feet more are withdrawn than are naturally
recharged.
California experienced one of the
most deadly and destructive wildfire years on record in 2018,
with several major fires occurring in the wildland-urban
interface (WUI). These areas, where communities are in close
proximity to undeveloped land at high risk of wildfire, have felt
devastating effects of these disasters, including direct impacts
to water infrastructure and supplies.
One panel at our 2019 Water
Summit Oct. 30 in Sacramento will feature speakers
from water agencies who came face-to-face with two major fires:
The Camp Fire that destroyed most of the town of Paradise in
Northern California, and the Woolsey Fire in the Southern
California coastal mountains. They’ll talk about their
experiences and what lessons they learned.
The southern part of California’s Central Coast from San Luis Obispo County to Ventura County, home to about 1.5 million people, is blessed with a pleasing Mediterranean climate and a picturesque terrain. Yet while its unique geography abounds in beauty, the area perpetually struggles with drought.
Indeed, while the rest of California breathed a sigh of relief with the return of wet weather after the severe drought of 2012–2016, places such as Santa Barbara still grappled with dry conditions.
Atmospheric rivers, the narrow bands
of moisture that ferry precipitation across the Pacific Ocean to
the West Coast, are necessary to keep California’s water
reservoirs full.
However, some of them are dangerous because the extreme rainfall
and wind can cause catastrophic flooding and damage, much
like what happened in 2017 with Oroville Dam’s spillway.
Learn the latest about atmospheric river research and forecasting
at our 2019 Water
Summit on Oct. 30 in Sacramento, where
prominent research meteorologist Marty Ralph will give the
opening keynote.
With a key deadline for the
Sustainable Groundwater Management Act in January, one of the
featured panels at our Oct.
30thWater
Summit will focus on how regions around California
are crafting groundwater sustainability plans and working on
innovative ways to fill aquifers.
The theme for this year’s Water Summit, “Water Year 2020: A Year
of Reckoning,” reflects critical upcoming events in California
water, including the imminent Jan. 31, 2020 deadline for
groundwater sustainability plans (GSPs) in high- and
medium-priority basins.
Our event calendar is an excellent
resource for keeping up with water events in California and the
West.
Groundwater is top of mind for many water managers as they
prepare to meet next January’s deadline for submitting
sustainability plans required under California’s Sustainable
Groundwater Management Act. We have several upcoming featured
events listed on our calendar that focus on a variety of relevant
groundwater topics:
Registration opens today for the
Water Education Foundation’s 36th annual Water
Summit, set for Oct. 30 in Sacramento. This year’s
theme, Water Year 2020: A Year of Reckoning,
reflects fast-approaching deadlines for the State Groundwater
Management Act as well as the pressing need for new approaches to
water management as California and the West weather intensified
flooding, fire and drought. To register for this can’t-miss
event, visit our Water Summit
event page.
Registration includes a full day of discussions by leading
stakeholders and policymakers on key issues, as well as coffee,
materials, gourmet lunch and an outdoor reception by the
Sacramento River that will offer the opportunity to network with
speakers and other attendees. The summit also features a silent
auction to benefit our Water Leaders program featuring
items up for bid such as kayaking trips, hotel stays and lunches
with key people in the water world.
Summer is a good time to take a
break, relax and enjoy some of the great beaches, waterways and
watersheds around California and the West. We hope you’re getting
a chance to do plenty of that this July.
But in the weekly sprint through work, it’s easy to miss
some interesting nuggets you might want to read. So while we’re
taking a publishing break to work on other water articles planned
for later this year, we want to help you catch up on
Western Water stories from the first half of this year
that you might have missed.
Our 36th annual
Water Summit,
happening Oct. 30 in Sacramento, will feature the theme “Water
Year 2020: A Year of Reckoning,” reflecting upcoming regulatory
deadlines and efforts to improve water management and policy in
the face of natural disasters.
The Summit will feature top policymakers and leading stakeholders
providing the latest information and a variety of viewpoints on
issues affecting water across California and the West.
One of California Gov. Gavin
Newsom’s first actions after taking office was to appoint Wade
Crowfoot as Natural Resources Agency secretary. Then, within
weeks, the governor laid out an ambitious water agenda that
Crowfoot, 45, is now charged with executing.
That agenda includes the governor’s desire for a “fresh approach”
on water, scaling back the conveyance plan in the Sacramento-San
Joaquin Delta and calling for more water recycling, expanded
floodplains in the Central Valley and more groundwater recharge.
Groundwater helped make Kern County
the king of California agricultural production, with a $7 billion
annual array of crops that help feed the nation. That success has
come at a price, however. Decades of unchecked groundwater
pumping in the county and elsewhere across the state have left
some aquifers severely depleted. Now, the county’s water managers
have less than a year left to devise a plan that manages and
protects groundwater for the long term, yet ensures that Kern
County’s economy can continue to thrive, even with less water.

Although Santa Monica may be the most aggressive Southern California water provider to wean itself from imported supplies, it is hardly the only one looking to remake its water portfolio.
In Los Angeles, a city of about 4 million people, efforts are underway to dramatically slash purchases of imported water while boosting the amount from recycling, stormwater capture, groundwater cleanup and conservation. Mayor Eric Garcetti in 2014 announced a plan to reduce the city’s purchase of imported water from Metropolitan Water District by one-half by 2025 and to provide one-half of the city’s supply from local sources by 2035. (The city considers its Eastern Sierra supplies as imported water.)
Imported water from the Sierra
Nevada and the Colorado River built Southern California. Yet as
drought, climate change and environmental concerns render those
supplies increasingly at risk, the Southland’s cities have ramped
up their efforts to rely more on local sources and less on
imported water.
Far and away the most ambitious goal has been set by the city of
Santa Monica, which in 2014 embarked on a course to be virtually
water independent through local sources by 2023. In the 1990s,
Santa Monica was completely dependent on imported water. Now, it
derives more than 70 percent of its water locally.
The whims of political fate decided
in 2018 that state bond money would not be forthcoming to help
repair the subsidence-damaged parts of Friant-Kern Canal, the
152-mile conduit that conveys water from the San Joaquin River to
farms that fuel a multibillion-dollar agricultural economy along
the east side of the fertile San Joaquin Valley.
The growing leadership of women in water. The Colorado River’s persistent drought and efforts to sign off on a plan to avert worse shortfalls of water from the river. And in California’s Central Valley, promising solutions to vexing water resource challenges.
These were among the topics that Western Water news explored in 2018.
We’re already planning a full slate of stories for 2019. You can sign up here to be alerted when new stories are published. In the meantime, take a look at what we dove into in 2018:
This 2-day, 1-night tour offered participants the opportunity to
learn about water issues affecting California’s scenic Central
Coast and efforts to solve some of the challenges of a region
struggling to be sustainable with limited local supplies that
have potential applications statewide.
In the universe of California water, Tim Quinn is a professor emeritus. Quinn has seen — and been a key player in — a lot of major California water issues since he began his water career 40 years ago as a young economist with the Rand Corporation, then later as deputy general manager with the Metropolitan Water District of Southern California, and finally as executive director of the Association of California Water Agencies. In December, the 66-year-old will retire from ACWA.
In 1983, a landmark California Supreme Court ruling extended the public trust doctrine to tributary creeks that feed Mono Lake, which is a navigable water body even though the creeks themselves were not. The ruling marked a dramatic shift in water law and forced Los Angeles to cut back its take of water from those creeks in the Eastern Sierra to preserve the lake.
Now, a state appellate court has for the first time extended that same public trust doctrine to groundwater that feeds a navigable river, in this case the Scott River flowing through a picturesque valley of farms and alfalfa in Siskiyou County in the northern reaches of California.
This tour explored the Sacramento River and its tributaries
through a scenic landscape as participants learned about the
issues associated with a key source for the state’s water supply.
All together, the river and its tributaries supply 35 percent of
California’s water and feed into two major projects: the State
Water Project and the federal Central Valley Project. Tour
participants got an on-site update of Oroville Dam spillway
repairs.
There’s going to be a new governor
in California next year – and a host of challenges both old and
new involving the state’s most vital natural resource, water.
So what should be the next governor’s water priorities?
That was one of the questions put to more than 150 participants
during a wrap-up session at the end of the Water Education
Foundation’s Sept. 20 Water Summit in Sacramento.
More than a decade in the making, an
ambitious plan to deal with the vexing problem of salt and
nitrates in the soils that seep into key groundwater basins of
the Central Valley is moving toward implementation. But its
authors are not who you might expect.
An unusual collaboration of agricultural interests, cities, water
agencies and environmental justice advocates collaborated for
years to find common ground to address a set of problems that
have rendered family wells undrinkable and some soil virtually
unusable for farming.
As California embarks on its unprecedented mission to harness groundwater pumping, the Arizona desert may provide one guide that local managers can look to as they seek to arrest years of overdraft.
Groundwater is stressed by a demand that often outpaces natural and artificial recharge. In California, awareness of groundwater’s importance resulted in the landmark Sustainable Groundwater Management Act in 2014 that aims to have the most severely depleted basins in a state of balance in about 20 years.
Spurred by drought and a major
policy shift, groundwater management has assumed an unprecedented
mantle of importance in California. Local agencies in the
hardest-hit areas of groundwater depletion are drawing plans to
halt overdraft and bring stressed aquifers to the road of
recovery.
Along the way, an army of experts has been enlisted to help
characterize the extent of the problem and how the Sustainable
Groundwater Management Act of 2014 is implemented in a manner
that reflects its original intent.

California voters may experience a sense of déjà vu this year when they are asked twice in the same year to consider water bonds — one in June, the other headed to the November ballot.
Both tackle a variety of water issues, from helping disadvantaged communities get clean drinking water to making flood management improvements. But they avoid more controversial proposals, such as new surface storage, and they propose to do some very different things to appeal to different constituencies.

participants got an on-site update of repair efforts on the
Oroville Dam spillway.
Participants of this tour snaked along the San Joaquin River to
learn firsthand about one of the nation’s largest and most
expensive river restoration projects.
The San Joaquin River was the focus of one of the most
contentious legal battles in California water history,
ending in a 2006 settlement between the federal government,
Friant Water Users Authority and a coalition of environmental
groups.
Groundwater replenishment happens
through direct recharge and in-lieu recharge. Water used for
direct recharge most often comes from flood flows, water
conservation, recycled water, desalination and water
transfers.
One of the wettest years in California history that ended a
record five-year drought has rejuvenated the call for new storage
to be built above and below ground.
In a state that depends on large surface water reservoirs to help
store water before moving it hundreds of miles to where it is
used, a wet year after a long drought has some people yearning
for a place to sock away some of those flood flows for when they
are needed.
Sinkholes are caused by erosion of
rocks beneath soil’s surface. Groundwater dissolves soft
rocks such as gypsum, salt and limestone, leaving gaps in the
originally solid structure. This is exacerbated when water is
acidic from contact with carbon dioxide or acid rain. Even
humidity can play a major role in destabilizing water
underground.
Irrigation is the artificial supply
of water to grow crops or plants. Obtained from either surface or groundwater, it optimizes
agricultural production when the amount of rain and where it
falls is insufficient. Different irrigation
systems are not necessarily mutually exclusive, but in
practical use are often combined. Much of the agriculture in
California and the West relies on irrigation.
The United States
Geographical Survey (USGS) defines freshwater as containing
less than 1,000 milligrams per liter dissolved solids. However,
500 milligrams per liter is usually the cutoff for municipal and
commercial use. Most of the Earth’s water is saline, 97.5
percent with only 2.5 percent fresh.
Springs are where groundwater becomes surface water, acting as openings
where subsurface water can discharge onto the ground or directly
into other water bodies. They can also be considered the
consequence of an overflowing
aquifer. As a result, springs often serve as headwaters to streams.
Potable water, also known as
drinking water, comes from surface and ground sources and is
treated to levels that that meet state and federal standards for
consumption.
Water from natural sources is treated for microorganisms,
bacteria, toxic chemicals, viruses and fecal matter. Drinking
raw, untreated water can cause gastrointestinal problems such as
diarrhea, vomiting or fever.
Extensometers are among the most valuable devices hydrogeologists
use to measure subsidence, but most people – even water
professionals – have never seen one. They are sensitive and
carefully calibrated, so they are kept under lock and key and are
often in remote locations on private property.
During our California
Groundwater Tour Oct. 5-6, you will see two types of
extensometers used by the California Department of Water
Resources to monitor changes in elevation caused by groundwater
overdraft.
Flowing into the heart of the Mojave Desert, the Mojave River
exists mostly underground. Surface channels are usually dry
absent occasional groundwater surfacing and flooding
from extreme weather events like El Niño.
Alluvium generally refers to the clay, silt, sand and gravel that
are deposited by a stream, creek or other water body.
Alluvium is found around deltas and rivers, frequently
making soils very fertile. Alternatively, “colluvium” refers to
the accumulation at the base of hills, brought there from runoff
(as opposed to a water body). The Oxnard Plain in Ventura
County is a visible alluvial plain, where floodplains have
drifted over time due to gradual deposits of alluvium, a feature
also present in Red Rock Canyon State Park in Kern County.
A new era of groundwater management
began in 2014 with the passage of the Sustainable Groundwater
Management Act (SGMA), which aims for local and regional agencies
to develop and implement sustainable groundwater management
plans with the state as the backstop.
SGMA defines “sustainable groundwater management” as the
“management and use of groundwater in a manner that can be
maintained during the planning and implementation horizon without
causing undesirable results.”
This issue looks at remote sensing applications and how satellite
information enables analysts to get a better understanding of
snowpack, how much water a plant actually uses, groundwater
levels, levee stability and more.
This handbook provides crucial
background information on the Sustainable Groundwater Management
Act, signed into law in 2014 by Gov. Jerry Brown. The handbook
also includes a section on options for new governance.

The 28-page Layperson’s Guide to Groundwater is an in-depth,
easy-to-understand publication that provides background and
perspective on groundwater. The guide explains what groundwater
is – not an underground network of rivers and lakes! – and the
history of its use in California.

– its impact on water users in the urban and agricultural sector
and the steps being taken to prepare for another dry year should
it arrive.
Statewide, groundwater provides about 30 percent of California’s
water supply, with some regions more dependent on it than others.
In drier years, groundwater provides a higher percentage of the
water supply. Groundwater is less known than surface water but no
less important. Its potential for helping to meet the state’s
growing water demand has spurred greater attention toward gaining
a better understanding of its overall value. This issue of
Western Water examines groundwater storage and its increasing
importance in California’s future water policy.
This issue of Western Water examines the issue of California
groundwater management, in light of recent attention focused on
the subject through legislative actions and the release of the
draft Bulletin 118. In addition to providing an overview of
groundwater and management options, it offers a glimpse of what
the future may hold and some background information on
groundwater hydrology and law.

Many Californians don’t realize that when they turn on the
faucet, the water that flows out could come from a source close
to home or one hundreds of miles away. Most people take their
water for granted; not thinking about the elaborate systems and
testing that go into delivering clean, plentiful water to
households throughout the state. Where drinking water comes from,
how it’s treated, and what people can do to protect its quality
are highlighted in this 2007 PBS documentary narrated by actress

A 30-minute version of the 2007 PBS documentary Drinking Water:
Quenching the Public Thirst. This DVD is ideal for showing at
community forums and speaking engagements to help the public
understand the complex issues surrounding the elaborate systems
and testing that go into delivering clean, plentiful water to
households throughout the state.
Water truly has shaped California into the great state it is
today. And if it is water that made California great, it’s the
fight over – and with – water that also makes it so critically
important. In efforts to remap California’s circulatory system,
there have been some critical events that had a profound impact
on California’s water history. These turning points not only
forced a re-evaluation of water, but continue to impact the lives
of every Californian. This 2005 PBS documentary offers a
historical and current look at the major water issues that shaped
the state we know today. Includes a 12-page viewer’s guide with
background information, historic timeline and a teacher’s lesson.
This 7-minute DVD is designed to teach children in grades 5-12
about where storm water goes – and why it is so important to
clean up trash, use pesticides and fertilizers wisely, and
prevent other chemicals from going down the storm drain. The
video’s teenage actors explain the water cycle and the difference
between sewer drains and storm drains, how storm drain water is
not treated prior to running into a river or other waterway. The
teens also offer a list of BMPs – best management practices that
homeowners can do to prevent storm water pollution.
Fashioned after the popular California Water Map, this 24×36-inch
poster was extensively re-designed in 2017 to better illustrate
the value and use of groundwater in California, the main types of
aquifers, and the connection between groundwater and surface
water.
Water as a renewable resource is depicted in this 18×24 inch
poster. Water is renewed again and again by the natural
hydrologic cycle where water evaporates, transpires from plants,
rises to form clouds, and returns to the earth as precipitation.
Excellent for elementary school classroom use.
The 20-page Layperson’s Guide to Water Marketing provides
background information on water rights, types of transfers and
critical policy issues surrounding this topic. First published in
1996, the 2005 version offers expanded information on
groundwater banking and conjunctive use, Colorado River
transfers and the role of private companies in California’s
developing water market.

The 24-page Layperson’s Guide to the State Water Project provides
an overview of the California-funded and constructed State Water
Project.
The State Water Project is best known for the 444-mile-long
aqueduct that provides water from the Delta to San Joaquin Valley
agriculture and southern California cities. The guide contains
information about the project’s history and facilities.
The 24-page Layperson’s Guide to Integrated Regional Water
Management (IRWM) is an in-depth, easy-to-understand publication
that provides background information on the principles of IRWM,
its funding history and how it differs from the traditional water
management approach.
The 24-page Layperson’s Guide to California Water provides an
excellent overview of the history of water development and use in
California. It includes sections on flood management; the state,
federal and Colorado River delivery systems; Delta issues; water
rights; environmental issues; water quality; and options for
stretching the water supply such as water marketing and
conjunctive use. New in this 10th edition of the guide is a
section on the human need for water.
The 28-page Layperson’s Guide to Nevada Water provides an
overview of the history of water development and use in Nevada.
It includes sections on Nevada’s water rights laws, the history
of the Truckee and Carson rivers, water supplies for the Las
Vegas area, groundwater, water quality, environmental issues and
today’s water supply challenges.
Seawater intrusion can harm groundwater quality in a variety of
places, both coastal and inland, throughout California.
Along the coast, seawater intrusion into aquifers is connected to overdrafting of
groundwater. Additionally, in the interior, groundwater
pumping can draw up salty water from ancient seawater isolated in
subsurface sediments.
Overdraft occurs when, over a period of years, more water is
pumped from a groundwater basin than is replaced from all sources
– such as rainfall, irrigation water, streams fed by mountain
runoff and intentional recharge. [See also Hydrologic Cycle.]
While many of its individual aquifers are not overdrafted,
California as a whole uses more groundwater than is replaced.
The treatment of groundwater— the primary source of drinking
water and irrigation water in many parts of the United States —
varies from community to community, and even from well to well
within a city depending on what contaminants the water contains.
In California, one-half of the state’s population drinks water
drawn from underground sources [the remainder is provided by
surface water].
Groundwater management is recognized
as critical to supporting the long-term viability of California’s
aquifers and protecting the
nearby surface waters that are connected to groundwater.
California has considered, but not implemented, a comprehensive
groundwater strategy many
times over the last century.
One hundred years ago, the California Conservation Commission
considered adding groundwater regulation into the Water
Commission Act of 1913. After hearings were held, it was
decided to leave groundwater rights out of the Water Code.
California, like most arid Western states, has a complex system
of surface water rights
that accounts for nearly all of the water in rivers and streams.
Groundwater banking is a process of diverting floodwaters or
other surface water into
an aquifer where it can be
stored until it is needed later. In a twist of fate, the space
made available by emptying some aquifers opened the door for the
banking activities used so extensively today.
When multiple parties withdraw water from the same aquifer,
groundwater pumpers can ask the court to adjudicate, or hear
arguments for and against, to better define the rights that
various entities have to use groundwater resources. This is known
as groundwater adjudication. [See also California
water rights and Groundwater Law.]
If California were flat, its groundwater would be enough to flood
the entire state 8 feet deep. The enormous cache of underground
water helped the state become the nation’s top agricultural
producer. Groundwater also provides a critical hedge against
drought to sustain California’s overall water supply.
In years of average precipitation, about 40 percent of the
state’s water supply comes from underground. During a drought,
the amount can approach 60 percent.
For something so largely hidden from view, groundwater is an
important and controversial part of California’s water supply
picture. How it should be managed and whether it becomes part of
overarching state regulation is a topic of strong debate.
In early June, environmentalists and Delta water agencies sued
the California Department of Water Resources (DWR) and the Kern
County Water Agency (KCWA) over the validity of the transfer of
the Kern Water Bank, a huge underground reservoir that supplies
water to farms and cities locally and outside the area. The suit,
which culminates a decade-long controversy involving multiple
issues of state and local jurisdictional authority, has put the
spotlight on groundwater banking – an important but controversial
water management practice in many areas of California.
Groundwater, out of sight and out of mind to most people, is
taking on an increased role in California’s water future.
Often overlooked and misunderstood, groundwater’s profile is
being elevated as various scenarios combine to cloud the water
supply outlook. A dry 2006-2007 water year (downtown Los Angeles
received a record low amount of rain), crisis conditions in the
Sacramento-San Joaquin Delta and the mounting evidence of climate
change have invigorated efforts to further utilize aquifers as a
reliable source of water supply.
When you drink the water, remember the spring. – Chinese proverb
Water is everywhere. Viewed from outer space, the Earth radiates
a blue glow from the oceans that dominate its surface. Atop the
sea and land, huge clouds of water vapor swirl around the globe,
propelling the weather system that sustains life. Along the way,
water, which an ancient sage called “the noblest of elements,”
transforms from vapor to liquid and to solid form as it falls
from the atmosphere to the surface, trickles below ground and
ultimately returns skyward.
Traditionally treated as two separate resources, surface water
and groundwater are increasingly linked in California as water
leaders search for a way to close the gap between water demand
and water supply. Although some water districts have coordinated
use of surface water and groundwater for years, conjunctive use
has become the catchphrase when it comes to developing additional
water supply for the 21st century.
